PROCESS OF UNITING METAL BODIES.

Specification of Letters Patent.

Patented May 29, 1917.

Application filed March 81, 191 5. Serial No. 18,267.

To all whom it may concern:

Be it known that I, ARCHER W.R 1or1anns,, a citizen of the United States, residing at- Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certaln new and useful Im rovement in Processes of Uniting Metal odies, of which the followin is a. full, clear, and exact descript on, re erence being had to the accompanying drawings.

This invention relates to processes for uniting metallic bodies by electric welding and more particularly to a process for unitin two metallic members or bodies (one of wfiich may surround the other.) The 111 vention disclosed herein is shown as used for the purpose of uniting the head of a barrel to one of the-ends thereof; and, while the articularly well adapted to the metallic arrel art, it will be understood that I do not propose to limit the use-of my invention to this particular field, as it will be evident that it is capable of much more general application.

It is-the general object of the invention to provide a process whereby metallic bodies or members ma be united in a partlcularly eflicient an economical manner. Further and more generally stated, the inven'- tion may be defined as consisting of the combinationsof-steps set forth in the claims hereto annexed and exemplified in the drawings forming part hereof, wherein Figure 1 represent a central vertical sectional view taken through a portion of a'barrel and showing the mannerin which thehead is inserted and welded in place therein;

1 Fig. 2'is a fragmentary sectional View illus- I trating a modification of the invention shown in Fig. 1; and Fig. 3 1s a view, Slmllar to Fig. 2, showing a still further modification.

Describing in detail and with the use of reference characters the particular embodiments of my invention disclosed herein, 1 denotes the body'of a barrel or other metallic article the barrelbeing; shown as a cylindrical nec 2. Within the neck of the barrel there is shown a head said head comprising the closure plate 3 and a c lindrical' ange 4. In Fi 1, the head is. s own as applled within t check, of the barrel with the plate 3 down and the flan ro'ectin upwardly. 1

It ig iiitende d to electrically weld the flange and neck together, after which the flange and neck will referably be rolled inwardly to form a tu e, indicated in dotted lines at 5, which tube will engage the plate 3 in a circular line located between the center and the periphery of the plate, sub

stantiall as pointed out and claimed in theapplication of J. H. Foster filed March 10,

bead or rib projects within the neck is necessarily exaggerated in the drawing for the purpose of illustration. In actual practice, I have found that a projection of 2/100 to 3/100 inch for this bead or rib will produce satisfactory results.

The barrel head, having been inserted with a driving fit into the neck-2, encounters the rib or bead 6. In order to insert the head farther, it is forced in by means of a suitable press until the top of the flange 4 is flush, or substantially flush, with the top of the neck 2. This will bring the bead or rib 6 preferably slightly above the plate 3. This insures aline contact between the flange 4 and the neck 2, and this line contact provides an ideal condition for electrically weldin together the ba'rrel head and neck. Int e drawings, the wheel electrodes of the electric-welding apparatus are indicated at 7 and 8 and are arranged to contact respectively with the outside of the neck 2 in the line of the rib or bead 6 and with the inside of the flange 4 in line with said rib or bead. The rib or bead 6 is provided by rolling or pressing the metal, and this compactin operation secures a uniform ga e of t e metal through the rib or bead an hence a' line contact for the welding operation. Furthermore the rib or bead 6 provides a surface which can be quickly cleaned prior to welding. In brief,

this operation provides the three conditions been united by electrically welding along the line of contact, the flangeand neck may be rolled inwardly in the manner indicated purpose explained hereinbes the rib or bead 9 is carried by the head The flange instead of by the barrel neck. amount of projection of this bead or Ilb will preferably be the same as that of the bead or rib 6 in Fig. 1, and the parts will be electrically welded in the same manner as is the case with the construction shown in Fig. I.

In Fig. 3 there is shown a still further modification of the invention wherein the barrel head is inverted with the plate 3 substantially flush with the end ofthe neck 2 and the flange 4 projecting inwardly or downwardly. The flange 4 in this case is provided with the outwardly projecting'r-ib or bead 10 similar to the rib or bead 9'but located closely adjacent to the plate 3. This arrangement has the advantage over that,

shown in Fig. 2 that the head has to be moved by a hydraulic press only the short distance required to move the rib from the top of the neck 2 to a point where the plate 3 will be substantially flush with the top of the ,neck. x

The manner herein disclosed of uniting metallic articles has proven in actual operation to be extremely efficient, securing-an absolutely tight and permanent joint between such. parts and accomplishing this result in an extreinel .economical manner.

Having t us described my invention, what I claim is an outermetallic member which consists in providingone of said members with a bead which is presented toward and adapted to engage the other member, the parts being of such diameter that the bead will engage its coiiperating member under pressure thereby to, secure a line contact therebetween, and lectrically welding said members together a ng such line of contact. 7 21' The process of uniting a pair of metal members which are adapted normally to fit snuglytlie onewithin the other, said process consist' in providing one of'said members with a ead presented toward the other member and adapted to engage the latter member under pressure, and electrically weldin said members together alon line 0 contact between said bead an adjacent engaging member. 3. The process of uniting a pair of metal -members which are adapted normally to fit snugly the onewithin the other, which process consists in providing "one of said members with a'continuous bead presented tothe ward the other body, forcing the bodies toan inwardly presented circumferential bead, 1'. The process of uniting an inner and.

.the the rels and 11 e metallic objects which consists ward the other member and adapted to engage the latter member under ressure, and electrically welding said mem ers together along the line of contact between said bead and the adjacent engaging member.

4. The process of uniting concentric me- Y tallic bodies which consists in providing one of said bodies with a continuous circumferential bead presented toward and adapted to engage the other body under pressure whereby a line contact is secured between said bead and such other body and electrically welding said bodies along such line of contact.

The process of uniting concentric inner and outer metallic bodies which consists in. making the inner body of a diameter which will enable it to fit snugly within the outer body, providing one of said bodies with a circumferential bead presented together whereby a line contact is secured between the bead and the cooperating body, and electrically welding said bodies along such line of contact.
